TL431KCS-TP

Overview

The TL431KCS-TP is a programmable precision shunt regulator manufactured by Micro Commercial Components (MCC). It functions as an adjustable voltage reference with a minimum fixed output of 2.495V and a maximum operating voltage of 36V. The device supports an output current of up to 150 mA and features a tight initial accuracy of ±0.4%. Packaged in a SOT-23 surface-mount case, it serves as a linear voltage regulator within the PMIC category.
